Answer:
1,-1,3,-3
Step-by-step explanation:
your P is the first number or the number with the highest exponent, your Q is the last number or the number with no variables. So you make a list of what multiplies to your P's and what multiplies to your Q's and you divide your P list by Q. So 3 is made by -1,1,-3,3 and -1 is made by -1,1. So dividing that you get your list of -3,-1,1,3
Answer:
d + q = 50
0.10d + 0.25q = 7.30
Step-by-step explanation:
Since all of the 50 coins are dimes and quarters, we can write the equation:
d + q = 50, where d is the number of dimes and q is the number of quarters
Now, we know that dimes are 10 cents, or $0.10 and quarters are 25 cents, or $0.25. So, if we multiply 0.10 by d, we get the total value of the dimes, and if we multiply 0.25 by q, we get the total value of the quarters. The total value of all dimes and quarters is 7.30, so we have the equation:
0.10d + 0.25q = 7.30
Thus, the system is:
d + q = 50
0.10d + 0.25q = 7.30
